DAVID E. ENGLE, OF JACKSONVILLE, (WIND RIDGE P. O.,) PENNSYLVANIA.

COMBINED FORGE AND STEAM-BOILER.

SPECIFICATION formingpart of Letters Patent No. 227,744, dated May 18, 1880. Application filed January 8, 1880.

To all whom it may concern:

Be it known that 1, DAVID E. ENGLE, of Jacksonville, (Wind Ridge P. 0. in the county of Greene and State of Pennsylvania, have invented a new and useful Improvement in Oombined Forges and Steam-Boilers, of which the following is a specification.

Figure 1, Sheet 1, is a sectional elevation of the improvement. Fig. 2, Sheet 2, is a sectional plan view taken through the line as m, Fig. 1. 1

Similar letters of reference indicate corresponding parts.

The object of this invention is to utilize theheat developed in forge-fires to generate steam for driving a fan-blower and other machinery.

A represents the forge, which may be constructed for one, two, three, or four fires, as may be required. The drawings show a forge constructed for two fires. B is an upright flue-boiler, which is placed in the forge A.

The fire-chamber O of the boiler is made with double walls, the space between the walls forming a water-space and being connected with the water-space of the boiler B.

The grate-bars D of the boiler B are made hollow, and theircavities are connected with the water-space of the fire-chamber 0, so that the water will circulate through the said gratebars. E are the places for the forge-fires, which are placed at the sides of the boiler B; and in the boiler B, directly opposite the fire-places E, are formed openings F, leading into the upper part of the fire-chamber 0, so that the smoke and other heated products of combustion of the forge-fires may pass into the firechamber 0, and thence through the boiler to utilize the heat developed in the said fires for generating steam in the boiler B.

The openings F are provided with doors Gr, so that the opening F opposite any tire-place E that is not in use may be closed. In the bottom of each fire-place E is placed a tuyere, H, which is made hollow, and its cavity is connected with the water-space of the firechamber 0, so that the tuyere may be kept cool by the circulation of the water in the boiler B.

I are the air-pipes leading to the tuyeres H from the fan-blower, and which are provided at their upper ends with ball-valves J. The stems K of the ball valves J have screwthreads out upon them, pass through screwholes iuthe air-pipes I or other suitable supports, and have cranks L formed upon or attached to their lower ends, so that by turning the said cranks L the valves J can be adjusted to regulate the air-blast.

Theboiler Bis designed to be supplied with all the usual appliances of steam-boilers.

Having thus described my invention, I claim as new and desire to secure by Letters Patentv The above-described device, consisting of the steam-boiler B, the boiler tire-chamber O, the forge fire-places E, connected with said chamber by openings F, and the tuyeres H, connected by pipes I with said fire-places, as shown and described.
